New York state and local municipalities may have lost millions of dollars of revenue after ticket-writing state troopers, who patrol the Thruway and interstates, were reassigned to help with 9/11-related duties, it was reported yesterday.

A lack of officers resulted in about 90,000 fewer tickets being issued over a four-month period, the Albany Times Union said.

In the city alone, 500 troopers were deployed to guard bridges and tunnels and assist with traffic control, while other troopers patrolled state power plants, Canadian-border crossing points and bridges, he said.

Troopers issued over 20,000 more tickets in September 2000 than September 2001, and the skid, beginning on the day of the terror attacks, continued through December, the Times Union noted.
